Water: Fish & Shellfish

Shellfish Protection


We lead or participate in a variety of programs and activities that help protect waters that support shellfish. This website is not a comprehensive list. If you have specific questions or if you are not able to find what you are looking for, please let us know.

We are directed by the Clean Water Act to maintain "...water quality which provides for the protection and propagation of...shellfish..." (§101(a)(2)). Rather than structuring its programs to protect particular living resources, like shellfish, programs are structured by environmental media (e.g., surface or ground waters), sources of pollution (e.g., wastewater treatment plants), specific types of pollutants (e.g., pesticides), and tools to detect, prevent, or correct problems (e.g., water quality standards, nonpoint source control, watershed protection, industrial discharge permits, and financial assistance. Through these and other mechanisms, we are able to work with other governmental and nongovernmental groups to reduce the impacts of pollution sources on the nation's aquatic resources such as shellfish.
